Stormwater Restoration

Client

Private Neighborhood Association

Location

Potomac, MD

Year Started

2025

Scope

  • Remove and replace damaged stormwater pipes

  • Rebuild the eroded stream pathway

  • Stabilize banks and prevent further erosion


After a severe thunderstorm in late July caused heavy erosion and redirected the stream bed, RemacUSA, Inc. was called in to restore the natural flow, replace damaged infrastructure, and protect neighboring properties from future flood risks.


Services Performed

Stormwater Remediation & Stream Realignment

  • Excavated and regraded the eroded stream bed to reestablish a stable flow path

  • Reconstructed and compacted stream banks using clean fill and natural contours to resist future washouts

✅ Pipe Removal & Replacement

  • Safely removed collapsed or undersized storm pipes contributing to flow restrictions

  • Installed larger, corrosion-resistant HDPE piping to handle future high-volume runoff events

Erosion & Sediment Control (ESC)

  • Installed silt fencing and check dams prior to ground disturbance

  • Deployed riprap and turf reinforcement matting post-restoration to stabilize stream edges

✅ Site Access & Neighborhood Coordination

  • Created temporary access paths for machinery with minimal impact to residential properties

  • Provided daily briefings and updates to homeowners’ association during execution


Challenges & Solutions

Challenge

The July 2025 thunderstorm caused excessive water velocity that deeply scoured the stream banks, displaced boulders, and widened the channel by several feet, damaging nearby lawns and undermining footpath access.

Solution

RemacUSA used topographic assessment tools and pre-storm maps to realign the stream to its original path. Erosion-resistant fill was compacted in layers to rebuild the banks, and geotextile fabric was used below the riprap to prevent future undermining.


Materials Recycled

♻️ Concrete & Debris

  • Old broken pipe sections were removed and sent to a certified concrete recycling facility in Montgomery County

♻️ Excavated Soil & Boulders

  • Clean soil was reused onsite for grading and slope support

  • Displaced native boulders were reintroduced into the stream to slow water flow and promote natural dispersion


Final Outcome

RemacUSA restored the stream to a controlled, naturalized flow, protecting nearby homes from future erosion while enhancing the overall appearance of the landscape. The upgraded piping now accommodates greater water volume, and the reinforced banks provide long-term durability.

The homeowners’ association commended RemacUSA for swift response, respectful coordination with neighbors, and leaving the site cleaner than it was before.
